I'm more interested in if it is allowed to cool down or something. My RSP2Pro was sitting with USB power available overnight but the PC shut down. When I fired it up to check out the signal reception at 1090, prior to starting dump1090, the signals appeared to be coming in somewhat below the expected location. Over a couple of minutes, they appeared to stabilize at the correct frequency, as if the RSP2Pro was warming up... Hence the question...
